Safety integrated
Safety Integrated functions
The integrated safety functions of SINAMICS provide highly
effective application-oriented protection for personnel and
machinery. The Safety Integrated functions are implemented
electronically and therefore offer short response times in
comparison to solutions with externally implemented
monitoring functions.
The trend toward greater complexity and increasing
modularity of machines is increasingly seeing a shift in
safety functions away from the classical central safety
functions (for example, shutdown of the complete machine
using a main switch) and into the machine control system
and the drives. Frequently, this also significantly increases
the productivity. This is because, for instance, equipping
times can be reduced and during these equipping times,
depending on the machine type, other parts can still
continue to produce.
Integrated safety functions act much faster than those of
a conventional design. The safety of a machine is
increased further with Safety Integrated. Furthermore,
thanks to the faster method of operation, safety measures
controlled by integrated safety systems are perceived as
less of a hindrance by the machine operator, therefore
significantly reducing the motivation to consciously bypass
safety functions.
The safety functions in the device and communication
via PROFIsafe have already been certified. This simplifies
configuring the safety functions and especially the
acceptance of the plant or system by an authorized testing
body when compared to safety solutions made up of
individual safety components.
Legal framework
Machine and plant builders must ensure that their
machines or plants neither present risks due to electric
shock, heat or radiation nor due to functional faults. In
Europe, for example, compliance with the machinery
directive is legally stipulated by the EU industrial
safety directive.
In order to ensure compliance with this directive, it is
recommended that the corresponding harmonized
European standards are applied. This initiates the
assumption of \conformity and gives manufacturers and
operators the legal security when complying with both
national regulations and EU directives. The machine
manufacturer uses the CE marking to document the
compliance with all relevant directives and regulations in
the free movement of goods.
Safety-related standards
Functional safety is specified in various standards.
IEC 12100 and IEC 14121-1, for example, are
concerned with the design and risk assessment of machines.
IEC 62061 (only applicable for electrical and electronic
control systems) and IEC 13849-1 (previously EN 954-1)
define the functional and safety-related requirements of
control systems with relevance to safety.
The above-mentioned standards define different safety
requirements that the machine has to satisfy in accordance
with the risk, frequency of a dangerous situation, probability
of occurrence and the opportunities for recognizing
impending danger.
• ISO 13849-1: Control Category 1...4
• ISO 13849-1: Performance Level PL a … e
• IEC 62061: Safety Integrity Level SIL 1 … 3
Safety functions integrated in the drive with SINAMICS
The safety functions integrated in SINAMICS satisfy the
requirements of
• Control Category 3 according to ISO 13849-1
• Safety Integrity Level (SIL) 2 according to IEC 61508
• Performance Level (PL) d according to ISO 13849-1
In addition, the Safety Integrated functions of SINAMICS
are generally certified by independent institutes. An up-to-
date list of certified components is available on request
from your local Siemens office.
